Abstract

According to a first aspect of the invention there is provided a catheter assembly (30). A lumen (33) extends through the catheter assembly and terminates with an exit port (34). The lumen being configured to receive a guide wire (36) therein. The catheter assembly comprises a flexible distal segment (46) having a predetermined length and a first predetermined outer diameter, a proximal segment (48) having a second outer diameter greater than that of the first outer diameter, and an intermediate tapered section (44) between the first proximal segment and the distal segment.
